By considering these factors, EWG provides a comprehensive rating system that helps consumers make informed decisions about their sunscreen choices.
The Importance of Broad-Spectrum Protection and SPF 30
When it comes to protecting your skin from the sun, broad-spectrum protection is essential. This means that the sunscreen must protect against both UVA and UVB rays. UVA rays can cause premature aging and skin cancer, while UVB rays are a primary cause of sunburn.
To ensure you’re getting adequate protection, look for a sunscreen with a Sun Protection Factor (SPF) of at least 30.
For the average person, the skin needs 30 minutes of time to burn, so a sunscreen with SPF 30 will protect for about 500 minutes, according to the American Academy of Dermatology.
The Role of the FDA in Regulating Sunscreen Effectiveness and Ingredient Safety
The FDA plays a crucial role in regulating the effectiveness and safety of sunscreens in the United States. To ensure that sunscreen products meet certain standards, the FDA has established guidelines for their composition, labeling, and testing.
The FDA has also approved several active ingredients for use in sunscreens, including oxybenzone, avobenzone, and zinc oxide. However, the FDA has also restricted the use of certain ingredients, such as retinyl palmitate, due to concerns about their potential health risks.
Examples of Sunscreen Products Certified by the Skin Cancer Foundation
The Skin Cancer Foundation, a leading organization in the fight against skin cancer, has certified several sunscreen products for their effectiveness and safety. Some examples include:

FAQ Resource
What is the difference between a physical sunscreen and a chemical sunscreen?
Physical sunscreens, also known as mineral sunscreens, work by creating a physical barrier on the skin’s surface to block UV rays, whereas chemical sunscreens absorb UV rays and convert them into heat, which is then released from the skin. Physical sunscreens are generally considered safer and more environmentally friendly.
How often should I reapply sunscreen during water activities?
It’s recommended to reapply sunscreen every 2 hours or immediately after swimming or sweating. However, if you’re engaging in activities that involve excessive sweating, you may need to reapply sunscreen more frequently, such as every 30-60 minutes.
What is a water-resistant sunscreen?
A water-resistant sunscreen is a sunscreen that remains effective on the skin even when exposed to water, such as swimming, sweating, or showering. However, it’s essential to note that water-resistant sunscreens are not waterproof and should still be reapplied after prolonged exposure to water.
